Proper use
The ARGUS E25 MOD II actuator is
intended for operating industrial con-
trols, such as, e.g. valves, gate valves,
butterfly valves and ball valves.
For other applications, please consult
the manufacturer.
In the event of improper use and any
resultant damage the manufacturer
accepts no liability. Such risks are
borne by the user alone.
Observing these Operating Instructions
is considered to be a part of proper use.
The units shall only be used within the
permissible electrical voltage and tem-
perature limits, taking chemical and
corrosive influences into account.
Observing and complying with all in-
structions in these Operating Instruc-
tions, in particular the safety instruc-
tions, is implicit in proper use.
Instructions and data in the documen-
tation supplied with the unit are con-
sidered to be an integral part of these
Operating Instructions.
Safety instructions on the unit or
on the valve to which it is fitted
must be observed.
The operating authority must ensure
that only the following activities are
carried out:
The maintenance operations de-
scribed in these Operating Instruc-
tions

Any other activities shall only be carried
out by personnel who have been spe-
cially trained and authorised by the
manufacturer.

regulate the rate of flow is improper
use.
Use of the actuator on a valve for which
it is not suitable is also improper use.
